煎茶岭金矿床的控矿因素分析及找矿方向

煎茶岭金矿床是属于与超基性岩有密切成因关系的浅成低温热液型矿床 (蚀变蛇纹岩型 ) ,主控断裂为 F4 51 ,与 F4 51 断裂相关的次级断裂和张性裂隙构造是最重要的容矿构造。矿体的形态、规模及矿石品位的变化与控矿构造的类型、产状和规模密切相关。对矿床的控矿因素的重新认识 ,将有利于指导矿山生产和拓宽找矿思路

ANALYSIS OF CONTROLLED AURIFEROUS MINERALIZATION IN JIANCHALING GOLD DEPOSIT AND EXPLORATION DIRECTION

Jianchaling gold deposit belongs to the epithermal low temperature hydrothermal deposit (altered serpentinite type) with the auriferous mineralization strongly associated with the ultra basic rock,and the fault F 45 1 is acknowledged as main controlling structure.It has been proved by the mining activity that the F 45 1 and the secondary splay and feather fracture are the key hosting structures.The shape,size and grade distribution of the orebody is significantly determined by the type,accurrence and scale of these structures.The reconsideration of the controlling factors of the deposit will facilitate mine production and exploration.
